Humacao County's Poor-condition bridges carry 220,068 vehicle crossings a day
That is 20.7% of the county's reported daily bridge traffic on 13% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 24,452 crossings a day against 12,384 for a Good-condition one. A Poor rating is a condition category, not a closure or a live safety judgement; it means the lowest applicable component rating is 4 or below.

20.3% of Humacao County's bridges have passed the 50-year mark
14 of the 69 bridges with a recorded construction year were built in 1974 or earlier. Age alone is not a defect: a well-maintained older bridge can rate Good, and 26.1% of this county's inventory does. Even so, this older cohort is the population from which future Poor ratings are drawn, which is why the age profile below matters alongside the condition split above.
Cutoff derives from the 2024 release year minus a 50-year design life. Source: FHWA National Bridge Inventory, 2024 release.
One structure carries 18.7% of the county's Poor-condition bridge traffic
PR 30R over PR 909, built 1976, carries 41,100 vehicles a day, the most of any Poor-rated structure here. The county's Poor-condition exposure is concentrated rather than evenly spread, so the 9-bridge count understates how much of the daily burden sits on a single crossing.
